To a/ZZ whom, t may concern:

Be it known that I, ISAAC N. VAN FELT, a citizen of the United States,residing at Lamar, in the county of Barton and State of Missouri, haveinvented a certain new and useful Improvement in Oultivators, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to an improvement in cultivators; and the objectof the invention is the provision of means whereby the operator mayreadily control the direction of movement of the cultivator withoutraising the teeth thereof from out of the ground.

A further object of the invention is the provision of an improved framefor the cultivator, whereby great rigidity will be obf tained, togetherwith simplicity of construction.

Other objects of the invention will be apparent from the descriptionhereinafter when read in connection with the accompanying drawings,forming a part hereof, wherein a preferable embodiment of my inventionis shown and wherein like letters of reference refer to similar parts inthe several views.

In the drawings, Figure l is a perspective view of my improvedcultivator. Fig. 2 is a horizontal section of my improved cultivatorwith parts broken away g and Fig. 3 is a longitudinal section thereof,parts being broken away.

Referring now more particularly to the drawings, A A designate thecultivatorbeams, the rear ends of which are substantially parallel andthe forward ends of which converge to the head-block B, to which theyare rigidly secured in any suitable manner. The beams A A are preferablyformed of a single piece of strap metal, which is bent at its centralportion to partially encircle the head-block B, said head-block beingprovided with a channeled portion b, adapted to receive the strap metalconstituting the beams A A. The beams A A are connected and strengthenedby means of the trussed braces C O. The braces O O are preferablyformedof a single piece of strap metal which is folded at its central portion,so as to partially encircle the head-block B and to lie within thechanneled portion b thereof underneath the strap which constitutes thebeams A A. The

` D, fitting therebetween, said block being provided along its sideswith channeled portions d for the reception of said braces. A bolt Eextends transversely through the braces and blocks and serves to rigidlyconnect the parts.

F F designate bearing-blocks which are `.provided withvertically-disposed apertures extending vertically therethrough, andwith the laterally-extending portions f The laterally-extending portionsf of the bearingblocks F F extend between the adjacent ends of the beamsA A and the braces B B and are secured therein by means of bolts whichpass through the ends of the beams and braces and the interposedprojections. From this construction it will be apparent that when thebearing-blocks become worn or broken they can readily be detached andreplaced with new ones.

G G designate cultivator-shovels of an type which are provided withstems g g, which are adapted to fit in the apertures f of thebearing-blocks F F and which are adjustably secured therein by means ofsetscrews f2, secured in the sides of the bearingblocks andadapted toimpinge against said stems. A similar cultivator e shovel G is mountedin an aperture D, formed in the block D, said shovel being adjustablysecured by a set-screw d', secured in a boss d2, surrounding theaperture D and adapted to impinge against the stem of the shovel.

H H designate bearing-blocks which are removably secured to the beamsAA,intermediate the ends thereof, by means of bolts h or in any othersuitable manner. The bearingblocks H I-I are provided with suitableapertures extending vertically therethrough, in which are adapted toloosely fit the stems i of the cutters I I. When the cutters I I aresecured in the bearing-blocks H H, the upper portions of the stems ithereof project beyond said bearing-blocks, and to the project- IOO ingportions of the stems are rigidly secured in any suitable manner theinwardly-extending arms K K, which are provided at their free ends withthe upturned portions k, for the purpose hereinafter more particularlyset forth. The cutters I I are in the form or runners and have theirforward ends rounded, so as to readily ride over any obstructions whichthey are incapable of cutting through.

L designates a cutter similar in form to the cutters I I, the stem Z ofwhich is journaled in a vertically-disposed aperture b in thebearing-block B, so as to turn freely therein, said cutter being heldtherein by a cotter-pin or other suitable fastening means.

M designates an arm which is pivotally connected at its central portionto the rear end of the block D, preferably by means of a stem m, whichextends downwardly therefrom and fits loosely in an aperture in saidblock. The ends of the arm M are provided with bifurcated portions fm@which loosely embrace the upturned portions k of the arms K K, securedto the cutters I I. The arm M is provided with the upwardly andrearwardly extending portions m2, to which are secured in any suitablemanner the handles N N. The arm M is also provided with theforwardlyextending projection m3, which when the arm M is moved travelsover the face of the block D between the lugs cl3 formed thereon, saidlugs serving to limit the movement of the arm in either direction.

O designates a draft-rod the rear end of which is provided with anaperture 0, adapted to engage a hook D2 on the forward portion of theblock D, and the forward portion of which extends between twoupwardly-extending curved plates P P, which are secured in any suitablemanner to the forward portion of the cultivator. The plates P P areprovided with a plurality of pairs of alined apertures p, and thedraft-rod O is provided with a single aperture therein, which isdesigned to be brought into alinement with any pair of the apertures p,according as it is desired to adjust the position of the draft-rod, apin p being utilized to`hold said draft-rod in its various positions ofadjustment. From this construction it will be apparent that the Adraftis from the block D, which is positioned in substantially the center ofthe cultivator,

and that the shovels will therefore be forced into engagement with theground, the depth of cut being regulated by adjusting the draftrod Obetween the plates P P.

In use when for any reason the operator desires to deflect the course ofthe cultivator he has only to shift the handles N N, which will turn thearm M, which through its connection with the arms K K will turn thecutters I I in the bearing-blocks H I-I, which will effect the desiredshifting of the course of the cultivator without raising the shovelsthereof from out of the ground.

I do not desire to limit myself to the precise form and constructionshown in the drawings, as it is obvious that many minor changes might bemade thereto without departing from the spirit of the invention.

What I claim, and desire to secure by Letters Patent, is-

1. A cultivator-frame comprising diverg- .ing beams, and truss-bracessecured to the inner sides of said beams and extending from the front tothe rear ends thereof, adjacent portions of said braces intermediate theends thereof being rigidly connected to each other.

2. A cultivator-frame comprising diverging beams, truss-braces securedto the inner sides of said beams and extending from the front to therear ends thereof, and a block interposed between and rigidly connectedto said braces intermediate the ends thereof.

3. A cultivator-frame comprising a piece of metal folded upon itself toform divergent beams, and bowed braces secured to the inner sides ofsaid beams, adjacent portions of said braces intermediate the endsthereof being rigidly connected to each other.

4. A cultivator-frame comprising a piece of metal folded upon itself toform divergent beams, a second piece of metal folded upon itself andsecured at its bend and ends to the inner side of the piece of metalforming the beams, the ortions of said second piece intermediate itsbend and ends being bent inwardly and rigidly connected to each other.
